Scientific Data

Western Blot Detection of Human Chymase/CMA1 antibody by Western Blot. View Larger

Detection of Human Chymase/CMA1 by Western Blot. Western blot shows lysates of human small intestine tissue. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Chymase/CMA1 Monoclonal Antibody (Catalog # MAB4099) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for Chymase/CMA1 at approximately 28 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Human Chymase/CMA1 ELISA Standard Curve. Recombinant Human Chymase/CMA1 protein was serially diluted 2-fold and captured by Mouse Anti-Human Chymase/CMA1 Monoclonal Antibody (MAB40991) coated on a Clear Polystyrene Microplate (DY990). Mouse Anti-Human Chymase/CMA1 Monoclonal Antibody (Catalog # MAB4099) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (DY998) followed by Substrate Solution (DY999) and stopping the enzymatic reaction with Stop Solution (DY994).

Background: Chymase/CMA1

Chymases are a group of chymotrypsin-like serine proteases secreted by mast cells (1). They are synthesized as inactive precursors containing a 2‑residue propeptide, which needs to be removed by dipeptidyl peptidase I/cathepsin C for the enzymatic activity (2). Human Chymase encoded by the CMA1 gene is known to be involved in hypertention and heart failure through its ability to convert angiotensin I (Ang I) to angiotensin II (Ang II), which plays a key role in the regulation of arterial pressure (3). In addition, it is also important in physiological and pathological conditions including inflammation, fibrosis and processing of cytokines (4). Therefore, designing a specific inhibitor for Chymase activity has been a pharmacologic strategy to develop therapeutic agents.
